Negative proposition? There is an x belonging to R, so x 2-x+1≤ 0. The true and false relationship among the original proposition, negative proposition, inverse proposition and inverse negative proposition is as follows:

Let two propositions be mutually negative propositions, and they have the same authenticity. Let two propositions be reciprocal propositions or reciprocal propositions, and its truth is irrelevant. Whether the original proposition and the inverted proposition are true or false, whether the inverted proposition is true or not.

A declarative sentence that can judge whether it is true or false is called a proposition, a correct proposition is called a true proposition, and a wrong proposition is called a false proposition. The original proposition and the inverse proposition are reciprocal, the negative proposition and the original proposition are reciprocal, the original proposition and the inverse proposition are reciprocal, and the inverse proposition and the inverse proposition are reciprocal. The detailed answer is shown in the figure. If you can't ask, it's not easy to write with satisfaction.
